Hi, here is the correct syntax: DSolve[{y'[x]+y[x]Tan[x]\[Equal]Sin[2x],y[0]\[Equal]2},y,x] Daniel learner wrote: > hi, > I am trying to solve y'+y tanx=sin(2x) > > i wrote NSolve[{Derivative[1][y][x]+y Tan[x]==Sin[2x]},y,x] but get > something like > > {{y->cot[x](sin[2x]-y`[x]}} > > I want to set a restraint to say y=2 when x=0, how shoud i do it? > > many thanks!!! >
